EXAMPLES

The following Examples were prepared analogously to the methods ofsynthesis described hereinbefore (as indicated in the Table). Thesecompounds are suitable for use as PDE4-inhibitors and have IC₅₀ valuesof less than or equal to 1 μmol. The inhibitions (in %) at 1 μM of theindividual Example substances are given in the following Tables ofExamples and were determined as follows:

The Scintillation Proximity Assay (SPA) (GE Healthcare, No. TRKQ7090)was carried out by using the different affinities of cyclic3″-5″-adenosinemonophosphate (cAMP, low affinity) and linear5′-adenosinemonophosphate (AMP, high affinity) for yttrium silicatescintillator beads. The cAMP specific phosphodiesterase (PDE) PDE4Bcleaves the 3′-phosphoester bond of tritium-labelled [H3]-cAMP to form[H3]-5′-AMP. This [H3]-AMP accumulates on the scintillator beads becauseof its higher affinity for them and causes scintillation events (flashesof light) which are measured in a Wallac Microbeta ScintillationCounter.

The experiment starts with a one-hour incubation of [H3]-cAMP with thePDE4B enzyme in assay buffer at 30° C., in each case once with theExample substance to be tested (in a concentration of 1 μM) and oncewithout the Example substance to be tested.

After this incubation, the reaction is stopped by the addition of thebeads. The beads have an opportunity to settle in the next 45 minutes,then the measurement is carried out in the Scintillation Counter. If thesubstance is capable of inhibiting the enzymatic activity of the PDE4B,less [H3]-AMP is produced during the incubation phase and fewerscintillation events can be measured. These results are expressed as thepercentage inhibition at a concentration of the test substance of 1 μM.

The Examples relate to compounds of the following formula 1,

Particular mentionshould be made of those applications for which the compounds accordingto the invention of formula 1 are preferably suited on account of theirpharmaceutical efficacy as PDE4 inhibitors. Examples include respiratoryor gastrointestinal diseases or complaints, inflammatory diseases of thejoints, skin or eyes, cancers, and also diseases of the peripheral orcentral nervous system.

Particular mention should be made of the prevention and treatment ofdiseases of the airways and of the lung which are accompanied byincreased mucus production, inflammations and/or obstructive diseases ofthe airways. Examples include acute, allergic or chronic bronchitis,chronic obstructive bronchitis (COPD), coughing, pulmonary emphysema,allergic or non-allergic rhinitis or sinusitis, chronic rhinitis orsinusitis, asthma, alveolitis, Farmer's disease, hyperreactive airways,infectious bronchitis or pneumonitis, paediatric asthma, bronchiectases,pulmonary fibrosis, ARDS (acute adult respiratory distress syndrome),bronchial oedema, pulmonary oedema, bronchitis, pneumonia orinterstitial pneumonia triggered by various causes, such as aspiration,inhalation of toxic gases, or bronchitis, pneumonia or interstitialpneumonia as a result of heart failure, irradiation, chemotherapy,cystic fibrosis or mucoviscidosis, or alpha1-antitrypsin deficiency.

Also deserving special mention is the treatment of inflammatory diseasesof the gastrointestinal tract. Examples include acute or chronicinflammatory changes in gall bladder inflammation, Crohn's disease,ulcerative colitis, inflammatory pseudopolyps, juvenile polyps, colitiscystica profunda, pneumatosis cystoides intestinales, diseases of thebile duct and gall bladder, e.g. gallstones and conglomerates, for thetreatment of inflammatory diseases of the joints such as rheumatoidarthritis or inflammatory diseases of the skin and eyes.

Preferential mention should also be made of the treatment of cancers.Examples include all forms of acute and chronic leukaemias such as acutelymphatic and acute myeloid leukaemia, chronic lymphatic and chronicmyeloid leukaemia as well as bone tumours such as e.g. osteosarcoma andall kinds of gliomas such as e.g. oligodendroglioma and glioblastoma.

Preferential mention should also be made of the prevention and treatmentof diseases of the peripheral or central nervous system. Examples ofthese include depression, bipolar or manic depression, acute and chronicanxiety states, schizophrenia, Alzheimer's disease, Parkinson's disease,acute and chronic multiple sclerosis or acute and chronic pain as wellas injuries to the brain caused by stroke, hypoxia or craniocerebraltrauma.

The preparations may be administered orally in the form of a tablet, asa powder, as a powder in a capsule (e.g. a hard gelatine capsule), as asolution or suspension. When administered by inhalation the activesubstance combination may be given as a powder, as an aqueous oraqueous-ethanolic solution or using a propellant gas formulation.

Preferably, therefore, pharmaceutical formulations are characterized bythe content of one or more compounds of formula 1 according to thepreferred embodiments above.

It is particularly preferable if the compounds of formula 1 areadministered orally, and it is also particularly preferable if they areadministered once or twice a day.

Capsules containing one or more active substances or combinations ofactive substances may for example be prepared by mixing the activesubstances with inert carriers such as lactose or sorbitol and packingthem into gelatine capsules. Suitable suppositories may be made forexample by mixing with carriers provided for this purpose, such asneutral fats or polyethyleneglycol or the derivatives thereof.

Excipients which may be used include, for example, water,pharmaceutically acceptable organic solvents such as paraffins (e.g.petroleum fractions), vegetable oils (e.g. groundnut or sesame oil),mono- or polyfunctional alcohols (e.g. ethanol or glycerol), carrierssuch as e.g. natural mineral powders (e.g. kaolins, clays, talc, chalk),synthetic mineral powders (e.g. highly dispersed silicic acid andsilicates), sugars (e.g. cane sugar, lactose and glucose), emulsifiers(e.g. lignin, spent sulphite liquors, methylcellulose, starch andpolyvinylpyrrolidone) and lubricants (e.g. magnesium stearate, talc,stearic acid and sodium lauryl sulphate).

For oral administration the tablets may, of course, contain, apart fromthe abovementioned carriers, additives such as sodium citrate, calciumcarbonate and dicalcium phosphate together with various additives suchas starch, preferably potato starch, gelatine and the like. Moreover,lubricants such as magnesium stearate, sodium lauryl sulphate and talcmay be used at the same time for the tabletting process. In the case ofaqueous suspensions the active substances may be combined with variousflavor enhancers or colorings in addition to the excipients mentionedabove.

It is also preferred if the compounds of formula 1 are administered byinhalation, particularly preferably if they are administered once ortwice a day. For this purpose, the compounds of formula 1 have to bemade available in forms suitable for inhalation. Inhalable preparationsinclude inhalable powders, propellant-containing metered-dose aerosolsor propellant-free inhalable solutions, which are optionally present inadmixture with conventional physiologically acceptable excipients.
